Stopping Sensipar®

This has been bothering me since yesterday. I was prescribed Sensipar, or cinacalcet hydrochloride about a month ago due to high calcium test results. I ran out of the medication right before yesterday’s appointment at UCLA, so I ordered a three-month refill with my online pharmacy. Here is the latest historical test result trend for calcium:

Everything was normal until mid-March, then above normal for the next three months. The only comment I received was to consume less dairy, while at the same time, I needed dairy to keep up my phosphorus levels. Often, I feel like I am an unwilling participant in a game where I need to achieve certain outputs by adjusting a few inputs that are connected via a black box. I my case, the inputs are food, exercise, and medication. The black box is the biological process inside my body, and the output is test results. The frustration is that the black box algorithms do not seem consistent over time. Sometimes test results change significantly without any obvious reasons, like the sudden increase/decrease in my creatinine. Here is my phosphorus result history:

It was too low post-transplant so I was prescribed a potassium/phosphorus supplement. Once the results were consistently above the low limit, I was told to stop taking the supplement. Since then, my phosphorus levels have continued to increase, with a huge jump in early June. That seems to have leveled off in the past few weeks. I do not remember any diet changes over the past month so I do not know what to do different if the numbers start changing rapidly again.
